Thank you for your input. We have extensive scales of "childhood adverse events" that try to capture a range of potentially damaging situations, and you are correct, they don't capture everything. On the other hand, if we extend the notion of trauma too far, it becomes meaningless, because everyone is exposed to some conditions that are less than ideal.

I hope that my comments were not misconstrued as ruling out any impact of trauma. We can however, at least partially identify when genetics, separate from any life experiences, are contributing to certain human bodily or mental health conditions. I only brought up blaming the mother in response to another question because the author in question does repeatedly and explicitly blame the mother for not matching what the child needs. Being a parent in a two-father household makes me at least somewhat attuned to blaming the mother issues.
